Look at the movement lines of their arms, and how close they are standing to each other. That is already the most awkward high-five in the universe. BRB’s right hand moves from his left shoulder, through the wings on his helmet to reach that position. What was he doing in the previous panel? Meanwhile, Quasar’s (that’s Quasar, right?) shoulders would have to move like those of an action figures with super-high-five-action for his “palm behind the head to full extension” technique to work.

I guess what I’m saying is that I’m not sure if the artist could have handled the sci-five.
